CORPORATION OF ILLINOIS ROOFING Application led January 30, 1928. SerialNo. 250,404.

The invention relates to what is known in the trade as prepared roofingwhich usually consists of av foundation sheet of fibrous charactercommonly called felt, which sheet is impregnated with a waterproofcomposition and, in many instances, has applied to one side a coating ofadhesive asphalt in which a layer of grit is embedded. This material isso flexible that very little force is required to bend it. Consequently,when laid upon a roof in overlapping courses the weather portions arelikely to be lifted by the elements, permitting rain, snow, or the like,to enter between the courses and hence through the roof.

The principal object of this invention is to provide a fastening meansand a method Yof laying that will permit the weather portions to beeffectively and economicall secured. The preferred embodiment o theinvention is illustrated in the 'accompanying7 drawings, in which fig. lisa plan view of a portion of a roo Fig. 2 isa section taken on the line2f-2 of Fig. 1, and

Fig. 3 is a perspective view of a portion of a roong element equippedwith fasteners of the preferred form. I

'However, this specific illustration and the correspondingly specificdescription are intended as illustrative only, for I realize that otherforms may be readily devised without departing from the spirit of theinvention and, therefore, the scope of the patent is to be found in theappended claims.

AThe supporting structure 10, shown best in Fig. 2, may be a roof or awall, and upon this is a covering formed of a plurality of 40overlapping courses of prepared roofing.

In this preferred form each ,strip or sheet includes a body portion 11and a plurality.

of tabs 12 of semi-hexagonal form separated by complemental spaces 13.On the lower side of each tab there is secured a fastener generallyindicated at 14. It is made of thin bendable sheet metal and comprises abase 15 anda tongue 16, the latter projecting beyond the'end of the tab.The base is cut on the lines 17 and 18 lto `form spurs, or

rivets, which may be inserted through the roofing and clinched on theopposite side.

In laying the roof the first course 19 is made of a plain sheet ofprepared roofing nailed to the supporting structure at 20.

In laying the next course a strip or sheet like that illustrated in Fig.3 is placed upside down beyond the eave and the tongues 16 insertedbeneath the rst course 19. The strip is then revolved about the eaveupwardly to take its proper position top side up with the tabs Hush withthe eave. During this revolution the tongues 16 are bent somewhat shortaround the lower edge of the first course and the blow of a hammer oneach fastener serves to embed the fastener in the roofing material andsecure each tab firmly to the first course.

In the second course a similar operation is performed, the strip beinglaid upside down. with its tabs in the spaces between the tabs of thesecond course and the tongues 16 under the body portion of the secondcourse. Next, it is revolved to take its proper position with the endsof the' tabs coinciding with the upper edges of the re- Cesses of thecourse below and its body por tion lying against the supportingstructure where it is nailed. This operation is continued until thecovering is completed, when a suitable comb, or ridge cap is applied.

By reason of the relatively short bends around the edges of the roofingin the course below each tab is securely fastened down wlithout thenecessity of using nails, or the li e.

The fasteners are easily produced by automatic machinery and applied tothe tabs at the roofing factory. They lie flat and lend themselves toconvenient packing and shipping. ,Y

I claim as my invention: c'

1. Flexible prepared roolin comprising a body portion, `a plurality otabs on one side of the body portion spaced by recesses ofcomplementalshape and a thin bendable metal fastener secured to theunderside of each tab, and projecting beyond the tab whereby suchroofing is adapted to be laid in overlapping courses with the tabs ofeach course staggered with the tabs of the course below, each coursebeing first placed u side down below the last course with t e fastenersinserted freely beneath the body of said last laid course and therespective tabs in the corresponding recesses and then rotated about theends of the tabs to bend the fasteners short about the edge of the bodyportion of the last laid course and press the course being laid intooverlapping relation with the course last laid.

2. A roofing strip comprising a body portion, spaced tabs thereon and athin flat bendable metal fastener secured to the underside of each tab,and projecting beyond and in the plane of the bottom of the tab, saidstrips being adapted to be laid in overlapping courses with the tabs ofeach course staggered with the tabs of the next adjacent courses and thefasteners adapted to be freely inserted upwardly beneath the bodyportion of the course below and to be bent by the .strip about the loweredge of the body portion when the strip is rotated upwardly intooverlapping relation with the course last laid.

3. A roofing strip comprising a body portion, and a plurality of thinbendable metal fasteners secured to the underside of the body along oneedge thereof, and projecting beyond and in the plane of the bottom ofthe strip, said strips being adapted to be laid in overlapping courseswith the fasteners adapted to be freely inserted upwardly beneath thebody portion of the course below and to be bent by the strip about thelower edge of the body portion when the strip is rotated upwardly intooverlapping relation with the course last laid.

In testimony whereof I aiix my signature.

ALBERT E. F. MOONE.
